The electrical connector has nothing to do with when the trans shifts. It only controls converter lockup. Shift points are controlled by the throttle valve cable adjustment. Sounds like yours is not adjusted properly.

Help with tcc connector

No one has a mid 80's c 10 with 305/350 ci engine with 700 r4 transmission?

Please excuse my brain fart. This is a 84 c 10 with 350 HO crate engine. The truck was painted along with firewall during restoration. My so called mechanic/painter left many things undone so trying to put it back together. The connector I'm talking about is at the other end of the four prong connector that goes in the 700 r 4 transmission. I know the connector should connect somewhere on the firewall. If I knew what wires feed it, I could splice it together and it should work - hopefully. Thanks. Bo

Not enough information on vehicle to provide an idea of where you need to plug in connector.

Trans connector is obvious on case... did You plug that in or not?

Year , make , model of this vehicle? Custom install? OEM install.

Engine swap? OEM engine?

Please give the members here some information so they can suggest solutions

I don't want to damage trans driving without lockup and it was rebuilt for stock tcc lockup. I tried to download pictures for past hour and just can't get my camera to cooperate. I would appreciate any input.

If you have a TH350C, the tranny won't be immediately (possibly never) damaged by not having the TC locked up, providing you have a tranny cooler.

Do you have a computer, or is this pre-computer ('80-back if GM)?

Details of what you have are needed.

Here is a wiring diagram.

If you have a stock 700r4 torque converter, it wont get hot enough to do damage, the engine will just rev about 200rpm more than if teh TCC was locked.

1984 C10 with TCC connector problems

Hi all! I just had a rebuild 700r4 installed in my truck and thought it was shifting a little soon. I checked the four prong connector at the trans and had no voltage at the connector. After following the wire - I found out it was not connected under the hood. i have a two prong connector yellow and light blue i think just hanging. There is no place for this to connect. i recently had my engine replaced and am wondering the he forgot to reinstall the connector where its supposed to go. He also painted my firewall. I have driven the truck for several miles without lockup. Is this going to hurt? Where would I hook the connector with the yellow and blue wire? Thanks. Bo
